I'm trying to update my Xperia X8 with the kernel E15_nAa-06b_2.6.29.6-nAa-06b. This update is required for MiniCM7-2.1.5. I used Flashtool v0.5.3.0, but the update "aborts" halfway. I performed this while the phone is in "recovery mode" as instructed (holding the back button while plugging the USB).

I assume that the kernel is made for an E15i model instead of the one I have (E15a). Can someone verify if this is true? The difference between the two models is the UTMS frequencies. Can someone please steer me into the right direction? What am I doing wrong? My phone currently has MiniCM7-2.0.7-X8, which works with the stock 2.1 kernel from Sony Ericsson.

I'm sure that there is a very important bug in v0.5.3. yesterday i flashed 2.1.1.c.0 on my phone (x8-E15i), after that i rooted by flashtool but when i wanted to install recovery, Flashtool couldn't install it and appeared a window to choose yo kind of recovery that window was empty. in fact i have no choice to select. so i canceled it and installed recovery by x8-toolbox. I like FlashTool but after v0.2.9.1 i couldn't use it completely.
